Years ago, I wondered what would happen if SMRT were to increase the number of train trips.
My argument back then was, passengers would leave for the train later. Meaning there will be more passengers at the station. As a result, the extra trips will cancel out the extra late passengers.
Today, after looking at the photo above, and the Clubsnap discussion, I realise that passengers are not going to give a damn. There are simply too many passengers for the extra trains to make any difference. Even if there's a difference, it's negligible.
If the extra train trips are for getting people to their destinations faster, there might be some measurable success. If they are to help reduce congestion, it's going to be a bit hard to prove.
